The application of CAN network in automobile control system

In view of the question which the automobile wiring become huge and complex,one kind of automobile network control system based on CAN-bus has designed.The system divides into two parts of high-speed CAN and the low-speed CAN,consisting of high-speed data acquisition modules,low-speed data acquisition module,instrument modules,lighting control module,PC monitoring module.The system completed the acquisition and processing of the analog signal,digital signal,switching signal and the display of oil mass,water temperature,rotational speed,vehicle speed,mileage and total mileage.The test showed that the data transmission rate of the high-speed CAN and low-speed CAN reached 500 kbps and 125 kbps respectively,to meet the real-time of engine,as well as ordinary real-time of automobile body.
